A 42-year-old woman presented with lower abdominal pain and fainting episodes 36 days after in vitro fertilisation and embryo transfer. Transvaginal ultrasound revealed a large amount of free fluid in the pouch of Douglas and no evidence of an intrauterine gestational sac or adnexal mass suggestive of ectopic pregnancy. A presumed haemorrhagic corpus luteal cyst was seen in the left ovary. Laparoscopic exploration revealed a left ovarian haemorrhagic mass, which was excised with preservation of the ovary. Histopathological examination confirmed an ovarian ectopic pregnancy (OEP). OEP is rare but potentially life-threatening, as it can lead to internal haemorrhage. Its diagnosis is challenging as preoperative and intraoperative findings can be evocative of the far more frequent haemorrhagic corpus luteal cyst and histopathology is often necessary to confirm the diagnosis. Early recognition of OEP is crucial to reduce maternal morbidity and mortality, and allow treatment that preserves fertility as much as possible.
